2. Intervention details
2.01	Human Factors: Any factor contributing to the occurrence and consequences of a crash or affects the behaviour of a road user			1.1 Enforcement
				1.2 Sanctions and Penalties
				1.3 Driver Training and Licensing
				1.4 Road user education, awareness building and public campaigns
2.02	VEHICLE FACTORS AND PROTECTIVE DEVICES: Different vehicles have different characteristics (size, weight….) and has different uses, hence, this intervention includes the effectiveness of vehicle factors and protective equipment (helmet, seatbelt…) in mitigating injuries in road crashes			1.1 Bicycle
				1.2 Powered Two‐wheeler
				1.3 Bus
				1.4 Truck
				1.5 Other Vehicles (excluding Car)
2.03	ROAD DESIGN, INFRASTRUCTURE AND TRAFFIC CONTROL: The design of different road infrastructure aiming to contribute significantly to traffic safety by reducing the number of crashes and crash severity.			1.1 Road design and urban form
				1.2 Protective Infrastructure
				1.3 Speed Control Infrastructure
				1.4 Bicycle, PTW and Pedestrian Paths
				1.5 Traffic Control and Junctions
				1.6 Work zones and tollbooths
2.04	POST‐CRASH PRE‐HOSPITAL CARE: The aim of post‐crash care is to avoid preventable death and disability, limit the severity of the injury and the suffering caused by it, and ensure the crash survivor's best possible recovery and reintegration into society. The way in which persons injured in road traffic crashes are dealt with following a crash determines their chances and the quality of survival			1.1 Extrication
				1.2 Ambulances (Road and helicopter) (including equipment)
				1.3 Level of medical personnel
				1.4 Drugs and medications
				1.5 First‐aid training of bystanders

				1.7 Time to hospital
2.05	LEGAL AND INSTITUTIONAL FRAMEWORK: The safety laws and regulations play a significant role in reducing injuries and fatalities among all road users. The safety institutions are responsible for the enforcement of these laws, hence their structure influences safety and road‐user behaviour			1.1 Pricing
				1.2 Safety institutions
				1.3 Motor Vehicle Insurance
				1.4 Laws
